🌟 Hello everyone! Today's topic: What is Photonics? 🌟 💥Photonics is the physical science of light waves, dealing with the generation, detection, and manipulation of light. It is known that light has a dual nature, exhibiting both wave-like and particle-like characteristics. The nature of light depends on the observed interaction. For example, bending or diffraction of light through a lens demonstrates its wave nature, while light produced or absorbed by solid-state devices like laser diodes or CCD detectors exhibits its particle nature. 🌠Photonics devices have a wide range of applications. Telecommunications heavily relies on photonics devices for fiber optic networks, significantly enhancing internet communication speed and capacity. Lighting has been revolutionized with the emergence of affordable, powerful LEDs that reduce energy consumption while providing high-quality, flexible lighting solutions. Solid-state lasers are now widely used in various fields, from medicine to industry. Lightweight, compact light sensors are found in diverse devices such as cellphone cameras, barcode scanners, printers, DVD players, and automotive sensors. Lastly, photonics-based computing aims to complement or replace traditional electronic circuits with optoelectronic circuits. 🎉Feel free to share your questions and thoughts in the comments and stay tuned for more information on photonics and keep following the light! 🌟 IEEE Photonics Society, AGU Photonics #Optics #Photonics #Research #Engineering #Education #Science #Lightstalk #AGUphotonics #IEEEPhotonics #EngineeringEducation #AGU #AbdullahGulUniversity

Photonics emerged as a field in 1960 with the invention of the laser, followed by the laser diode in the 1970s and the development of optical fibers for data transmission. These innovations paved the way for the telecommunications revolution and laid the foundation for the internet.   Although "Photonics" had been coined earlier, it only gained widespread use in the scientific community in the 1980s, coinciding with the adoption of fiber optic transmission by telecommunications networks. Bell Laboratories (Nokia) played a significant role in popularizing the term, and its usage was further solidified with the establishment of the IEEE Lasers and Electro-Optics Society's journal, Photonics Technology Letters.   Initially centred around telecommunications, Photonics has since expanded to encompass various scientific and technological applications, including laser manufacturing, biological and chemical sensing, medical diagnostics and therapy, display technology, and optical computing. Following the dot-com crash circa 2001, there has been a notable growth in non-telecom photonics applications, driven in part by companies seeking new application areas. The ongoing development of silicon photonics holds the promise of further expanding the field's growth potential.   Explore the world of Photonics by visiting www.photonicsnl.org #Photonics #Optics #PhotonicsNL #History #knowledge
